10 all whom it may concern.-

Be it known that I, WILLIAM EDGAR SIN- CLAIR, a citizen of the UnitedStates, residing at Mobile, in the county of Mobile and State ofAlabama, have made certain new and useful Improvements in Log-Carriers,of which the following is a specification.

My invention is an improvement in that class of log-carriers in whichthe draftanimals attached to a tongue and wheeled axle are utilized forlifting and handling logs, the tongue being adapted to slide in suitableguides and connected with a pivoted liftinglever, which in turn operateschains and grapples attached to the log or logs.

The chief objects of my invention are to reduce the draft heretoforerequired for raising the logs by the lift-lever and chains and also toenable the operation of loading and unloading to be more quicklyeffected.

The details of construction, arrangement, and operation of parts are ashereinafter described, and illustrated in the accompanying drawings, inwhich- Figure 1 is a vertical section of a wheeled log-carrierconstructed according to my invention. Fig. 2 is an end view of thesame. Fig. 3 is a longitudinal section of the log-carrier minus thewheels. Fig. 4 is a plan view minus the wheels. Fig. 5 is an enlargedtransverse section on the line 5 5 of Fig. 3. Fig. 6, Sheet 1, is aperspective view of the pivoted socket for the log-lifting lever.

In Figs. 1, 3, and 4 A indicates a tongue, B hounds in which the tongueis adapted to slide, and C an axle to which the hounds are attached.Bars D are applied to the hounds and axle, and upon these bars ispivoted a lever E, fixed in a metal socket F. The lever is pivoted so asto swing in line with the tongue, and its limit of movement is from thehorizontal to the vertical, or approximately so. The outer end of saidlever is connected by a chain E with a hook a, secured to the tongue A.A doubletree G is attached to the tongue at a point contiguous to thehook a, and in practice this will be provided with whiffletrees, towhich the tree will be connected in the usual way. The tongue A isprovided with a series of vertical perforations a (see Fig. 3) forreception of a locking-bolt H, which serves to prevent the tonguesliding backward when drawn out to any desired extent.

The front ends of the houndsB are provided with a cross-block B, fromwhich depend parallel side bars B these being connected at their lowerends by a cross-bolt I). (See Fig. 5.) In the bars B I arrange twoantifrictionrollers I I, one above and the other below the tongue A. Asshown in Fig. 3, the upper roller I is arranged in the block B, whichconnects the front ends of the hounds B. I arrange a thirdantifriction-roller I directly in front of the axle C, (see Fig. 3,) andthe tongue A rests on and runs in contact therewith. By means of theseantifriction-rollers I greatly relieve the friction, and therefore thedraft heretofore attendant upon and necessary for operating the tongueA. In other words, the tongue may be drawn out or pushed back with lessdraft and greater case than heretofore, so that the strain on the teamis greatly reduced and the loading or unloading may be more quicklyeffected.

. I have improved the socket or boot F, in which the lever proper, E, isheld-that is to say, I construct the socket with lateral extensions F,(see Fig. 6, Sheet 1,) which are forked and otherwise constructed insuch manner as to adapt them to receive and lock the log-lifting chainsJ. In other words, these lateral projections F form vertical oppositejaws between which the log-lifting chains may be placed and with whoselinks they engage, as will be readily understood. The jaws F being openon the upper side, it is apparent that the chains J may be very quicklyinserted or removed from them in the operation of raising or loweringlogs. It will be seen that since the jaws F are formed integrally withthe socket proper, F, they are strong and durable and not liable to bebroken in the exigencies of use. As shown in Figs. 1 and 3, the saidchains J are provided with grapples or hooks J in the usual way. Thechains pass over antifriction-rollers K, ar ranged in suitable bearingsat the rear of the bars D. (See Figs. 3 and 4.) The axle upon whichthese rollers K are mounted is journaled in open bearings, as shown inFigs. 1 and 3.

As in other log-carriers of this class, when the chains and grapples J Jhave been connected with a log upon starting the team the tongue A isdrawn forward, and the lever E is thus carried down from the verticalposition shown in Fig. 1 to the horizontal position shown in Fig. 3 andthe tongue is locked by the pin H and the lever secured by a chain L, asshown in Fig. 4. There being two chains J, two logs may be raised andtransported in this manner. Upon reaching the point of. delivery thechain L is first unhooked and then the chain E, so as to release the lever E. This allows the logs to drop to the ground, and upon removal ofthe locking-pin II the tongue A may be slid backward with ease in Viewof the antifriction-bearings provided for it. The weight of the tongue Ais always imposed on the rear antifriction-roller I and it engages orbears forcibly upon one or the other of the front rollers I I, accordingto conditions.

I provide for raising and transporting smaller logs than those to whichthe chains and grapples J J are ordinarily applied by means ofsupplemental chains M. (See Figs. 1, 2, and 3.) These are attached tocrossbolts N, held in eyebolts O, that pass through the axle O and itsbolster and the hounds. The opposite or free ends of the chains M may besupported by hooks P, secured to and pendent from the axle; but inraising the logs which these chains are adapted to carry the chains willbe engaged with the jaws F of the lever-socket F in the same manner asthe chains J.

The hooks P, before referred to, are also adapted to be utilized when alog has been grappled and raised by one of the chains J through theoperation of the lever, as before describedthat is to say, when a largelog has been raised by one chain J the hook P, which is adjacent to saidchain, maybe locked therewith for holding the log suspended, and thenthe upper end of the chain J may be released from the lever E, and thelatter may then be operated for raising another log by means of theopposite chain J.

By means of the construction and arrangement of parts before described Ihave improved log-carriers of the class to which mine belongs in severalparticulars which are very important in practice.

What I claim is- 1. In a log-carrier, the combination, with an axle andhounds provided with guides, of a slidable tongue, log-lifting chains, apivoted lever, and a chain connecting it with the aforesaid tongue, andbearings for the tongue consisting of two antifriction-rollers arrangedrespectively below and above the tongue in a front attachment of thehounds, and a rear antifriction-roller arranged adjacent to the axle andbeneath the tongue, substantially as described.

2. In a log-carrier, the combination of the axle, the hounds, a blockconnecting the front ends of the hounds, and parallel bars pendenttherefrom and provided with two antifriction-rollers arrangedtransversely and spaced apart, one above the other, and a rear guide forthe tongue, substantially as described.
